Biochemical processes, degrade relatively difficult, the biochemistry treatment time of staying longer, general using following biochemical processes
Step is processed：Pre-treatment waste water sequentially enters grid, regulating reservoir, breakdown of emulsion, two grades of sources of the gas, contact-oxidation pool degraded, precipitations
Pond, Electrooxidation tower, qualified discharge, wherein two grades source of the gas emissions carry out air supporting sludge, and in addition washing water is directly entered contact oxygen
Change pond degraded, the solidss that the solidss formed subsequently into follow-up process, sedimentation tank and air supporting sludge are formed are solidified
And dehydration, solidss can also carry out acidolysis, and the effluent part through Electrooxidation tower process is reflowable as air supporting sludge water, adopts
GB4287-2012 first discharge standards be can reach with above-mentioned processing procedure draining：COD is less than or equal to 80mg/l, and BOD is less than or equal to
20mg/l, SS be less than or equal to 50mg/l, PH6～9, but this processing method, due to exist in waste water organic oil emulsion, surface live
Property agent, difficult using general biochemical oxidation process degraded, so employ breakdown of emulsion and floatation process on stream, to remove
The COD of the 70-80% gone in waste water or so, is then processed in entrance bio-oxidation pond, long flow path, complex treatment process, if
There is exception in control, is susceptible to out excessive problem, and the discharge water after processing does not account for reuse yet, and water resource is not using
It is very abundant.

S2：Then, the waste water for removing solid phase waste flows into circulating water chennel, processes flat composite membrane group is entered by pump group
Heap, the slurry in waste water and oil preparation are removed, be finally completed purification formation can recycle-water, can recycle-water enter reuse tank.
In some embodiments, S2 can also be：The waste water for removing solid phase waste flows into circulating water chennel, is passing through pump group
Send into the soluble large molecule pollutant that RO films groups is removed in waste water, be finally completed purification formation can recycle-water, can recycle-water enter
Enter reuse tank.
In some embodiments, flat composite membrane group process heap in composite membrane can also be MBR film groups, EDI film groups,
UF films group or NF film groups.
In some embodiments, flat composite membrane group is provided with the regulating reservoir for regulating pondage and water quality before processing heap.
In some embodiments, flat composite membrane group to be processed and be additionally provided with blower fan at heap, and the air outlet of blower fan is provided with aeration
Ejector；The technical program can improve the contact surface of the time of staying of air and increase gas-liquid two-phase, improve the utilization of gas
Rate, saves the energy consumption of blower fan.
In some embodiments, right angle strainer is additionally provided with after machinery drum sieve.
It is an advantage of the current invention that：The machinery drum sieve that the technical program is adopted, can retain in waste water and be more than 5-100 μm
Solid formation, requires so as to improve the float for entering right angle strainer, is conducive to the efficiency for improving system equipment, simultaneously because greatly
Amount solid formation is trapped, and alleviates the load of subsequent technique process, is conducive to energy-conservation and improves the exception handling ability of equipment；Adopt
Heap is processed than General reactions device efficiency high with flat composite membrane group, and is conducive to the process of high density pollution thing, and use
Composite membrane group can be regenerated, and its stability for operating and service life are more excellent than general film, water stabilization, consolidating in water
Phase thing content is very low, eliminates Sedimentation tank, and reduces the discharge capacity of subsequent treatment sludge；Effluent quality can reach factory
Water supply standard, the utilization rate of water are high；Flow process using modular combination, can carry out flexible combination by water quality, water yield requirement completely,
Meet different process and and prescription.
Description of the drawings
Fig. 1 is the flow chart of the high concentration wastewater treatment method that a kind of refining process of the invention is produced.
Specific embodiment
With reference to Figure of description, the present invention is described in more detail.
The high concentration wastewater treatment method that a kind of refining process as shown in Figure 1 is produced, comprises the steps：
